WIRE-COIL MACHINE.

SPECIFICATION forming part of Letters Patent No. 594,535, dated November 30, 1897.-

' Application filed M81011 31,1897- Serial NO- 630,028. (N0 model.)

To aZZ whom it may concern..-

Be it known that we,HENRY M. JACKSON and GEORGE M. JAoKsoN, citizens of the United States, residing at Reading, in the county of Berks and State of Pennsylvania,have invented certain new and useful Improvements in Wire-Coil Machines; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in wire-coil machines-of that class in which the coil is fed onward by means of grooved rolls and in which the coil, after being inserted in the belt or other fabric, is flattened between serrated jaws.

The object of the invention is to provide certain improvements on the machine shown and described in Letters Patent No. 581,027, granted April20,1897,which machine is adapted to insert the coil into a leather belt and then flatten the coil flush with the surfaces of the belt, at the same time setting the convolutions of the coil at right angles to the axis of said coils.

The present invention shows these features as adapted to our new machine in connection 'with certain improvements, which we will proceed to describe in the following specification.

In the drawings herewith, Figure 1 is afront elevation of the machine. Fig. 2 is a longi tudinal sectional view on line a: a: of Fig. 1. Fig. 3 is a vertical sectional view on line y y of Fig. 1. Figs. 4 and 5 show one of the rolls in detail. Fig. 6 is a sectional view on line z z of Fig. 2.

The rolls A, B, and C in our machine are placed in the usual position, and the jaws D and E, as usual, are located just in front of them. These rolls are mounted in cars F, one on each end of the machine, which ears are pivotally secured to the lower jaw, as shown in Fig. 3. The rolls are formed at their feed end with a slight taper, so that when the coil is entered it will find its way between the rolls without difficulty. The lower roll 0 is provided with a circumferential rib or flange 0 the latter being located a short distance from the feeding end of the roll.

Said rib or flange is so arranged that when the end of the coil reaches it said end will be slightly deflected, so as to insure its striking the edge of the belt squarely immediately after leaving the groove next to said rib or seen that it is impossible for the coil to bend or be forced out of its true path. This is due to the fact of the belt being located immediately alongside of said rib, whereby the deflection of the coil caused by striking the belt improperly is prevented.

The rolls Band Cthat is, the rear and lower rolls-are grooved longitudinally near the outlet end thereof for about one-third of their circumference and the length of an ordinary needle, such as is used on this class of machines. The rolls are so set that these grooves b and a will register at every revolution of the rolls. The object of these grooves is that when it is desired to feed a coil of wire into a belt it is customary to first pass through said belt a coiled needle, so thatthe perforations will be ready to receive the coil when entered. When this needle has passed through the machine and reaches that portion of the rolls where they are grooved, it will drop out of the machine automatically and can be caught in any suitable receptacle provided for that purpose.

When it is desired to join two ends of leather, it is not necessary in all cases to insert a coil into each end and then join them, for the two ends can be placed between the jaws at the same time, one above the other, and a single coil entered into them. Then the jaws are opened, and the ears F, which carry the rolls, are thrown down to the position shown by dotted lines in Fig. 3, and one end of the belt is passed between the jaws, bringing the coil in position to be flattened.

Each roll in our machine is backed by a strengthening-rib a, b, and c, and the space between the roll and this rib is filled with Babbitt or other soft metal, thus giving it a bearing the whole of its length. The rolls are mounted eccentrically in projections g on these ribs, (see Fig. 6,) so as to give the proper movement when adjusted. In the rib backing the outer roll B we provide a slot 1), in which is located a vertical block L, through which passes a screw S. To the ends of this block are pivotallyseeured links l and Z, connecting, respectively, the ribs a and c of the rolls A and O. On the end of the screw S is provided a thumb-piece, by means of which the screw is turned, thus moving the block L forward or backward in the slot 1) and drawing the rolls A and O nearer to or farther away from the roll 13. This adjustment is desirable when different sizes of coils are used or when there is not sufficient friction to cause the coil to feed properly.

The jaws D and E are opened and closed by means of a lever ll, secured to the eccentrically-mounted shaft II. This shaft bears in a semicircular groove along the top of the upperjaw, and its eccentric ends are mounted in bearings 7L on either end of said jaw. On both ends of both jaws are provided lugs m, in which are secured bolts at. These bolts screw into the lugs on the upper jawand pass through the lugs of the lower jaw and are provided at their lower ends with nuts. There is also a guide-lug 0, pivoted to each end of the upper jaw, through which these bolts pass. Bya half-revolution of the shaft II the jaws are opened or closed, and the bolts n keep the jaws perfectly parallel. These jaws are formed with serrations t on their meeting faces nearly their full length and about half of their width. The other half of their faces are flat. \Vith this construction the coils can be pressed first between the serrated portions, forcing the convolution into the proper angle, and then between the flat portions and pressed into the belt, making the surfaces perfectly flush. A guide G is placed near the feed end of the lower jaw. This guide is so situated that when the belt is placed in the machine against it the coil will enter the edge of said belt immediately on leaving the rib c and when the belt is pulled forward, bringing the coil between the jaws, by keeping the belt against the guide the serrations of the jaws will be sure to engage the eonvolutions of the coils properly and not allow them to be forced out of line, and at the same time it will insure the coil being inserted into the end of the belt at right angles to its length.

It will be seen that in this construction we have striven to produce a machine that will be as nearlyautomatic in every particular as is possible, so that it will not require a skilled mechanic to operate it successfully.

The whole invention consists of the improved details of construction which we have just described and in the simplicity of operation caused by their application to the old machine. \Ve do not, therefore, wish to cover fully the construction of the machine as a whole; but

\Vhat we do claim, and desire to secure by Letters Patent, is-

1. A wire-coil machine having top and bottom jaws adapted to engage the coil and having serrations formed on a portion of their meeting faces, rolls mounted in swinging ears, backed by strengthening-ribs and adapted to feed said coil through a belt or other article, substantially as set forth.

2. A wire-coil machine having top and bottom jaws adapted to engage and flatten the coil, adjustable rolls mounted in swinging ears pivotally connected to the lower jaw, said rolls being adjustable by means of a movable block, and links located back of each roll and operated by a screw, substantially as set forth.

3. A wire-coil machine having top and bottom jaws adapted to engage and flatten the coil, adjustable rolls tapered at their feed ends and mounted in swinging ears pivotally secured to the lower jaw, one of said rolls provided with a circumferential rib or flange near its feed end, and the rear and lower rolls being formed with registering grooves near the outlet end thereof, substantially as set forth.

4. A wire-coil machine having top and bottom jaws adapted to engage and flatten the coil, said top jaw having upwardly-projecting ears h in which is an eccentrically-mounted shaft ll, guide-rods 7L secured in lugs on the ends of said jaws and adapted to travel in pivoted guides 0, the upper jaw being operated by means of a lever secured to the shaft II, and the lower jaw being provided with a guide G for the belt or other article, substantially as set forth.

In testimony whereof we affix our signatures in presence of two witnesses.
